FAQ - Vitamin D Light Therapy

What is Vitamin D Light Therapy?

We use the Sperti sunlamp that emits high-intensity ultraviolet-B (UVB) rays that trigger vitamin D production in the skin.  Sessions are usually 1-5 minutes in duration.


Can I just use a regular fluorescent lamp at home?

Regular fluorescent lamps are not powerful enough to generate vitamin D production. Also, other vitamin D lamps may not generate the UV spectrum that optimizes vitamin D production.


What can I expect during a Vitamin D Light Therapy session?

The Sperti Vitamin D lamp will be placed about 18” from your body. Maximum skin exposure is recommended. It is recommended to rotate so not to concentrate UV exposure in one area.  A timer will be set to a maximum of 5 minutes.  You will be asked to wear UV protective eyewear.  


What should I wear during a session?

Regular clothes is fine, however, the more skin that is exposed to the UV light, the more vitamin D your largest organ, your skin, can produce.  


Can I just take a vitamin D supplement instead?

Vitamin D supplements are one way to absorb the nutrient, however, absorption by the skin (the body’s largest organ) is the most effective. When taken orally, only a fraction (20-40% or less) of the essential nutrients are absorbed due to a variety of factors: unhealthy diet, insufficient essential nutrients, widespread prevalence of gastrointestinal problems, chronic illness and more. Vitamin D Light Therapy triggers production of the vitamin in your body, making it a more efficient and effective treatment.


What conditions are vitamin D deficiency associated with?

Vitamin D deficiency is associated with numerous conditions, including bone loss, osteoporosis, kidney disease, diabetes, stomach and intestine problems, lung disorders, depression, seasonal affective disorder (SAD), fatigue, acne, eczema and more.


Will I burn with this lamp?

We recommend that you rotate the parts of your body exposed to avoid burning and tanning.


Are the UV lights from the lamp safe?

To minimize skin damage, our lamp has a timer that limits exposure to five minutes.


How do I know if I’m deficient in vitamin D?

You can request a blood test at your physician’s office to determine your vitamin D blood levels. Our medical team can also create an order for your blood levels.


Can you overdose on vitamin D?

As with anything, we recommend a balance in life. Vitamin D can be toxic if taken in excess orally. When boosting the production of vitamin D thru the skin, one cannot overdose; the skin will simply stop making the vitamin. Please consult with your physician prior to starting any treatment.
